Primary Tumor

A primary tumor is a tumor growing at the anatomical site where tumor progression began and proceeded to yield a cancerous mass.

Famous quotes containing the word primary:

    “If a madman were to come into this room with a stick in his hand, no doubt we should pity the state of his mind; but our primary consideration would be to take care of ourselves. We should knock him down first, and pity him afterwards.”
    —Samuel Johnson (1709–1784)
